If their guess was right, then Seth had somehow attacked both women and then succeeded in incapacitating them and then sending them flying away, this was a possible reason as to why two 3rd stage cultivators would travel so far in the air and then simply crash to the ground.
This thought flowed through everyone's mind, and while there was also another option that explained the weird disappearance and appearance of the two women, nobody wanted to consider it.
Two 3rd stage Kaiser Cultivators, nobody wanted to accept the possibility that Seth had simultaneously killed such powerhouses as the consequences of such a feat on both them and the world were incalculable.
There was worry for the two women in their hearts, but they stood firm and warily watched Seth, ready to attack Seth immediately the order was given even if such an action would be a pointless sacrifice of their lives.
